SIPHON.

SPECIFICATION forming part of Letters Patent No. 565,729, dated August 11, 1896.

Application filed December 7, 1895. Serial No. 571,372. (No model.)

' To whom it may concern.-

Be it known that I, HARRY FOOI-IT, a citizen of the United States, residing at Reading, county of Berks,- State of Pennsylvania, have invented certain Improvements in Siphons, of which the following is a specification.

My invention relates to that class of siphons which are especially adapted for filling bottles from a reservoir, and more particularly to improved means for attaching the siphon to various sizes and forms of bottles, and regulating the heights to which the same are automatically filled.

Figure 1 is a sectional elevation showing a siphon provided with my improvement attached to a bottle having a mouth smaller than the stopper proper. Fig. 2 is a similar view showing the same applied to a bottle of larger size and indicating how the depth to which the bottle is filled may be regulated. Fig. 3 shows the main stopper in cross-section, and Fig. 4; shows the stopper extension in cross-section on line to m of Fig. 1.

A represents the liquid-tube, and B the airtube, of a well-known form of siphon, both of which are extended in practice sufficiently to connect with the reservoir of liquid from whichthe bottle E is to be filled. The stopper 0, as shown, is adjustably strung upon the liquid-tube A, the lower end A of which extends downward into the bottle to any desired extent.

The air-tube B is connected to an opening 0 of the stopper running parallel with that through which the liquid-tube passes. This arrangement necessitates a stopper of considerable size, as indicated in Fig. 3. In using the device as heretofore made the stopper 0 must enter the mouth e of a bottle, which is then filled from the connected reservoir in the usual manner by first exhausting air from the bottle by suction exerted through the tube B until the liquid-tube isfilled by the atmospheric pressure on the reservoir, and then allowing it to flow into the bottle until automatically stopped by the closure of the out let 0 in the stopper.

The main purpose of my improvement is to provide for conveniently filling bottles hav ing'smaller or different-shaped necks than the stopper 0 is adapted to enter, and, second, to permit regulation of the depth to which the bottle is automatically filled. To accomplish this, I provide a stopper extension D, preferably formed separately of rubber tubing, the lower end def which is small enough to engage the fluid-tube A, while the enlarged upper end at may be tightly stretched over the stopper 0, so as to form practically a part of the latter. An annular air-chamber F is thus formed between the liquid-tube A and the wall of the stopper extension which communicates through the opening 0 with the airtube 13 and is provided at or near its lower end with an opening (1' for the exit of air from the bottle E.

In using the siphon with my improvement attached it will be seen that it may be applied to a bottle having a mouth 6 of any size somewhat larger than the tube A, the stopper extension D being entered more or less until it is tight in the mouth of the bottle, as indicated in Fig. l, and the device operating as usual, the flow into the bottle being stopped as soon as the liquid rises to the height of y the air-exit cl. The height in the bottle at which this exit is closed may be regulated by moving the small end 01 of the stopper extension nearer to or farther away from the main stopper 0, as desired, as indicated in Fig. 2.

The area of the annular air-chamber F will be equal to that of the opening 0 in the stopper 0, though the latter be very little larger than the exterior diameter of the liquid-tube A, as shown in Figs. 3 and 4:, thus permitting the siphon to be attached to a very small-neck bottle without interfering at all with its operation. This, in connection with the advantage of easily regulating the point at which the flow of liquid is cut off, renders my improvement very useful, especially in view of its easy application to the ordinary construction of siphons, as described.

What I claim is- The combination with the air and liquid tubes, and the stopper with separate passages for said tubes, of a tubular extension of said stopper inclosin g the extended liquid-tube and forming an annular air-chamber around the same said tubular extension being independently adjustable upon the projecting liquid-tube to regulate the point of cut oif substantially as set forth.

In testimony whereof I affix my signature in presence of two witnesses.

HARRY FOCHT.
